> Regionservers get active master address from Zookeeper/Master registry and 
> tries to make RPC calls to master.
> For security concerns, regionservers might require making connection to a 
> different proxy port of master rather than it's original port retrieved from 
> Zookeeper.
> Configs:
>  # hbase.master.expose.proxy.port: Master can use this config (int) to expose 
> new proxy port on active and backup master znodes.
>  # hbase.client.consume.master.proxy.port: Clients/Regionservers can use this 
> config (boolean) to determine whether to connect to active master on new 
> proxy port that master has exposed or continue using original port of master 
> for connection.
